It looks quite nice, it's a lot of carbon fibre. It has a throttle flap to change over from the longer runners to the shorter path to generate low-midrange torque. Similar concept to the variable inlet tract of the E34 M5. Of anyone has owned one of those you know how much difference it makes when the variable inlet flap stops working.

It is very cost prohibitive given that there are really not any dyno tests nor any real world performance stats.

No kidding. When I had my E34 M5 I couldn't believe how much of a difference that little flap makes. Pretty amazing. But for this price, I would have to say my money would go to a S/C.

The german tuner Alpha-N is developing a carbon airbox for the M3 E9x. As far as I know, it should be ready somewhere in February. Their carbon parts are usually very high quality. I'm really looking forward to it.

As I stated Alpha-N is still working on the Airbox. It looks promising. Their carbon airboxes are usually of very high quality. Should be available in September. Here some photos:

P.S. The second photo is not the final version. It is still undergoing testing and dyno runs.

^^ hideous. Have fun paying a bunch of money to lose power by sucking in hot engine air.

It is not as if they are making an airbox for the first time. They already have quite a good reputation for their products and I doubt that they don't know what "hot air" and that it no bueno. So relax and wait for the results.

I've also asked one of the guys there about that issue especially on the left side, but he said that they are still testing and if there is the need to change something, they will certainly do it.

Apart from that their carbon airbox is autoclaved! Something which you can't find that easy.

I don't have anything to do with them. I'm just sharing the information I have, because this might be the first intake system for the E9x M3 which offers real power gains, apart from the sound.
